Question

我正在尝试按照教程为我的Django应用程序创建上传表单。我正在尝试这样做，以便我可以上传CSV文件，然后处理它。

我在/ upload /'str'对象中遇到TypeError是不可调用的

upload.html

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>Minimal Django File Upload Example</title>   
    </head>
    <body>
    <!-- List of uploaded uploads -->
    {% if uploads %}
        <ul>
        {% for upload in uploads %}
            <li><a href="{{ upload.csvfile.url }}">{{ upload.csvfile.name }}</a></li>
        {% endfor %}
        </ul>
    {% else %}
        <p>No uploads.</p>
    {% endif %}

        <!-- Upload form. Note enctype attribute! -->
        <form action="{% url 'upload' %}" method="post" enctype="multipart/form-data">
            {% csrf_token %}
            <p>{{ form.non_field_errors }}</p>
            <p>{{ form.csvfile.label_tag }} {{ form.csvfile.help_text }}</p>
            <p>
                {{ form.csvfile.errors }}
                {{ form.csvfile }}
            </p>
            <p><input type="submit" value="Upload" /></p>
        </form>
    </body>
</html>

views.py

def upload(request):
    # Handle file upload
    if request.method == 'POST':
        form = UploadForm(request.POST, request.FILES)
        if form.is_valid():
            newdoc = CSV(docfile=request.FILES['csvfile'])
            newdoc.save()
    else:
        form = UploadForm() # A empty, unbound form

models.py

class CSV(models.Model):
    file = models.FileField(upload_to='csv/')

forms.py

class UploadForm(forms.Form):
    csvfile = forms.FileField(
        label='Select a CSV file',
    )

urls.py

url(r'^admin/', include(admin.site.urls)),
url(r'^upload/$', 'upload', name='upload'),

知道为什么我会收到这个错误吗？有没有办法专门从调试页面找出它的含义？任何帮助表示赞赏
